ductor supports on transmission lines already in stalled. 1' Other objects and advantages will appear from the following description.

l' The invention is exemplified by the combina# tion and arrangement of parts shown in the oc- Acoinpanying drawing and described in the following specification, and it is more particularly pointed out in the appended claims;

In the drawing: y

Fig. 1 is an elevation of a dead end clamp having a conductor supported thereby and equipped with one embodiment of the present invention; Fig. 2 is av fragmentary, vertical, sectional view of the attachment shown in Fig. 1. Figs. 3, 4' and 5 are sections on lines 3-3, 4--4 and 5-5 respectively of Fig. 2.

Electrical conductors, and especially conductors of -large size, are subject to vibration, which has atendency in time to crystallize the conductor at its point of support' and cause breakage of the strands. Various devices have been designed to minimize or prevent this effect bygdamping out 'the vibrations and by distributing the bending of l 'tion of the conductor.

the conductor at its support over an extended por- One form of device for thisI purpose is shown in Patent #1,873,798, granted August 23, 1932 to Theodore Varney. The device described in that patent comprises a plurality of tapered bars or rods disposed about the conductor at'its point of support and extending along the conductor at either side of the support. The arrangement requires special clamping means for securing the reinforcing rods to the conductor and for attaching the bundle of rods with the enclosed conductor to the conductor. support.

iIn the embodiment of the invention shown in the drawing, the numeral II) designates a conductor clamp which may be similar to that shown 1n my prior patent #1,002,113. wnne 1' have The ar-v rangement makes it dicult or impossible to ap- 'ply the device t`o yconductors,'already installed.

shown the attachment applied to a dead end clamp, it is to be understood that it may be appliedA also in a like manner to suspension clamps distributed along the conductor. The invention comprises an extension member II having one end I2 shaped to t over the endof the clamp y I0 and provided with aprojecting portion I3 having a seat for receiving the reinforcing rods Il disposed about the conductor I5,4 The portion I2 is provided with laterally extending bosses I3 for receiving the ends of a U-bolt Il, which engages vthe upper portion of the clamp I0 and thus secures the attachment II firmly in position on thc end of the clamp I0. The end I2 of the clamp II is provided with projecting ridges I8 and I9 which provide grooves on the inner side of the attachment wall for receiving ribs and 2| respectively on the clamp Il). It will'be seen that this arrangement firmly secures the attachment II to the end ofthe clamp I0.so that it is rigidly held in position on the clamp and forms, in effect,

an extension on the end of the clamp. The projecting portion I3 is provided with aseat of proper size and contour to support the reinforc-V ing rods I5 on the conductor III and permit the' conductor to continue from the end of the clamp I0 without deflection. The keeper 22 engages the upper rods- I4 and is provided with ears 23 which extend into pockets 24 in the side walls of the extension I3 so as to provide overlapping portions with the side walls to hold the rods I4 in position upon the cable I5 and to clamp the rods rmly in the support I3 and tightly about the conductor I5. The keeper 22 is held in place by U-bolts 25 having nuts 26 for clamping` the 4portion extending beyond said support along said conductor, and flexible reinforcing rods carried by said extending portion and engaging said conductor beyond said extending portion for minimizing the effects of vibration of said conductor.

- 2. The combination with a conductor and a support therefor having a seat portion for receiving said conductor, of an attachment for said support' having a seat portion, one end of which is rigidly clamped to said support in overlapping relation to the seat portion of said support and the other end of which extends beyond said support along said conductor, and reinforcing meansl an attachment for securing said reinforcing means to said conductor and to said support, said attachment being disposed in overlapping relation with said support and with said reinforcing means, and clamped to said support and to sai'd reinforcing means.

4. The combination with a conductor and a support therefor having a seat for said conductor, of reinforcing means for said conductor compris- -ing rods having the ends thereof disposed in abutting relation to the end of said support, and an attachment for securing said rods to said conductor and to said support, said attachment having one end thereof shaped to conform to the outer surface of said support and having an extension overlapping the ends of said reinforcing rods, and means for clamping said attachment to said support and to said reinforcing rods in overlapping relation to the adjacent ends of said support and reinforcing rods.

5. The combination with a conductor and a. support therefor having a seat for said conductor, said support having external projections adjacent the end thereof, of an attachment having a recess therein shaped to conform to the outer surface of said support and having depressions for receiving the projections on said support, and means for clamping said attachment to said support, said attachment having a portion thereof extending beyond the end of said support and provided with a seat for receiving reinforcing means disposed about the conductor.

6. The combination with a conductor and a support therefor having a seat for said conductor, of reinforcing rods disposed about said conductor and having the ends thereof disposed in abutting relation to the end of said support, and an attachment for securing said ends to said con' ductor and to saidsupport, said attachment comprising a trough shaped member forming a seat having one end thereof shaped to conform to the outer surface of the end of said support, and having the other end thereof'shaped to engage said rods, and clamping means for securing said attachment to said support and for securing said rods in said seat. 4
